| Summary: | Growing ubiquity and safety relevance of embedded
systems strengthen the need to protect their functionality against
malicious attacks. Communication and system authentication
by digital signature schemes is a major issue in securing such
systems. This contribution presents a complete ECDSA signature
processing system over prime fields for bit lengths of up to 256
on reconfigurable hardware. By using dedicated hardware implementation,
the performance can be improved by up to two orders
of magnitude compared to microcontroller implementations. The
flexible system is tailored to serve as an autonomous subsystem
providing authentication transparent for any application. Integration
into a vehicle-to-vehicle communication system is shown
as an application example. |
